Abstract: A phase detection system includes a low-resolution sensor (200) and a high-resolution sensor (202) for monitoring an alternating current (AC) voltage. A phase detector (204) receives voltage samples from both the low-resolution sensor and the high-resolution sensor. The phase detector monitors the low-resolution sensor to detect approaching zero cross events (i.e., monitored voltage values approaching zero). In response to an approaching zero-cross event, the phase detector uses the magnitude of the high-resolution voltage samples measured on either side of the zero cross event to determine the phase of the monitored AC voltage.

Abstract: The method according to the invention, for monitoring and protecting alternating current threephase lines, comprises the following operations: a) finding the course of the three concatenate voltages (Vab, Vac, Vbc) between a phase and another phase; b) determining the three phase-differences (”Õab-ac, ”Õac-bc, ”Õab-bc) between the three pairs (Vab-Vac; Vab-Vbc; Vac-Vbc) of concatenate voltages; c) checking whether at least one of the three phase-differences (”Õab-ac, ”Õac-bc, ”Õab-bc) between the several pairs of concatenate voltages is comprised in its respective admissible phase-difference range. This allows providing protection and monitoring relais able to operate in a very wide range of line voltage rating. The invention also relates to a device arranged for carrying out such method.
